Reaction ball



FIG. 1 is a top view of the reaction ball showing my new design;

FIG. 2 is an elevation view thereof as seen from the front, rear, leftor right side;

FIG. 3 is an elevation view rotated 45° from FIG. 2; and,

FIG. 4 is a bottom plan view thereof.

The appearance within the unshaded circular regions forms no part of theclaimed design.

Left side, right side, and rear views of the reaction ball are identicalto the front view of FIG. 2. Thus, the left side, right side, and rearviews have not been shown.

CLAIM I claim the ornamental design for a reaction ball, as shown anddescribed.
